Abstract

The need on electricity increases annually while its supply decreases, meanwhile power plant has not increased. Process of building microhydro power plant needs scientifically experience and more time to give suitable result as it designed. Sengkaling Cross-flow Microhydro power plant resulted inappropriate electricity power compare with designed power plant. The design is mostly not in accordance with planned calculation. It is caused by the engineer who is not considering surrounding condition. Therefore, simulation is very important to be conducted that it only needs short time to the design maximally arranged. By simulation, building and assembling process can be conducted faster and decreases error risks. Simulation for this research used AUTODESK SIMULATION CFD.

Abstract

The condition of railroads is the main determinant of train safety. The recent railroads inspection conducted by the mechanic results inaccurate inspection and it cannot be conducted continuously. Therefore, this research develops the inspection by using Image Processing Method. Image processing facilitates and accelerates the measurement of railroads quality. This technique enables the automation of railroads measurement in continuous and faster process. It is as the inspection needs no direct measurement. The image processing conducted in this research uses edge detection method with filter disk 12. For collecting data, this research uses laser line and camera to capture figure of the railroads. Furthermore, the figure data is analyzed by using Matlab software. Output of image processing is graphic of the railroads surface that is analyzed to obtain its quality from its flatness. Result of railroads surface measurement by using image processing is averagely 3.61311 mm height and 55.6000 mm width. It is validated with manual measurement by the result of average height is 3.63 mm and average width is 5.5385 mm. The normal flatness of railroads by using image processing is 0.4488 mm. Inspection by using image processing is feasible as the alternative for substituting the manual process previously conducted.

Abstract

The utilization of natural resources as a metal inhibitor is widely researched. The extract of Calliandra leaves is one of the natural resources utilized to prevent the corrosion rate. It contains high tannins, which is a natural compound that can be utilized as an inhibitor of the corrosion rate. The research is aimed to find out the efficiency of Calliandra leaves extract as the natural inhibitor for steel ST-37. The experiment method is applied to vary the extract of Calliandra leaves in the corrosive medium. Meanwhile, the extraction of Calliandra leaves uses the maceration method. The extraction of Calliandra leaves with the solvent uses an evaporation process using a rotary vacuum evaporator. The extract used as the inhibitor is determined in 5%, 10%, and 20% of concentrations. The sample test of corrosion used is steel ST-37 with 4 × 4 cm of dimension and 0.2 cm of thickness. The best inhibition efficiency is 99.73% with an inhibition concentration of 20% in HCl. It shows that the extract of Calliandra leaves works well as an inhibitor, and it is efficient to inhibit the corrosion rate.

Abstract

Souvenir industry is the supporting aspect of tourism industry. As the one of creative economy industries, souvenir shows the characteristics of a region or a tourism place. This industry needs expertise and creativity, but there is an issue in the development of product variations with high expenses and the improvement of skills to create a product. The method to conduct this program is by conducting empowerment with participative and bottom-up approach. The participants are given electroforming training for souvenir industry. From the implementation of this program, the souvenir industry is given assistance through the training of electroforming technology to improve their creativity and souvenir production.Souvenir industry is the supporting aspect of tourism industry.
